After the laser process is finished, remove all of the cut parts from the laser. If necessary, clean the cut parts carefully with a slightly moistened cloth.
Insert the wide band from the bottom through the first slit so that the four small holes on the band are exactly over the four holes of the pin roll.
Now thread the narrow band through the four small holes so that the band crosses over on the upper side.
Turn the pencil roll over and knot the thin tape on the back. Then shorten the ends with scissors.
